WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 704,992, dated July 15,1902.

Application tiled October 14,1901. Serial No. 78,561. (No model To @ZZwhom, t may concern:

Be it known that I, CLAUDE B. WARNER, a citizen ofthe United States, anda resident of Avon, in the county of Fulton and State of Illinois,haveinvented a new'andlmproved Window-Screen, of which the following isa full, clear, and exact description. V

This invent-ion has forits object to provide novel details ofconstruction for windowscreens having sheet-metal frames that adapt thescreen-frame for adjustment to fit it for use in Windows of differentwidths.

A further object is to provide the screen Withahand-hole opening and aclosure therefor of novel construction.

The invention consists inthe novel construction and combination ofpart-s, as hereinafter described, anddeiined in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts `in all theiigures.

Figure lis a side elevation of the lower portion of a window-easementand an inner view of the improved screen held therein. Fig. 2 is anenlarged transverse sectional view of one of the framebars of thescreen, substanially on the line 2 2 in Fig. l. Fig. 8 is an enlargedsectional plan view showing the construction and connection of ahand-hole closure for the screen substantially on the line 3 3 in Fig.l. Fig. 4 is a perspective view of a modified hand-hole closure inposition on the lower portion cfa screen. Fig. 5 is a View of a splitkey which may be employed; and Fig. 6 is a like view with Fig. 1, butshowing the hand-hole closure represented in Fig. 4t positioned on thescreen.

The rectangular border-frame of the screen is constructed of sheet metalthat is rustproof, such as galvanized iron or steel plate of suitablethickness. Each side, top, and bottom frame-bar is composed of twosections 10 1l, that have slidable engagement one With the other. Thesection lO7 as best shown in Fig. 2, is bent from a plate-metal strip,so as to provide two parallel side Walls e, a, that are spaced apart byan integral transverse wall h and at their free edges are return bent toproduce two clip-flanges c, which are ad jacent to and extend parallelwith each other toward the spacing-Wall l). The complementary frame-barmember l1 is bent into U shape from a sheet-metal strip, the sidesthereof being so spaced apart in parallel planes as to adapt saidmemberto have a closely-iitted slida'ble engagementwithin the section 10, andenter its free edges in the channels that intervene the clip-flanges cand sides a.

It will be seen that the telescopic engagement of the members 10 1l,comprising each of the four frame-bars, may be longitudinally adjusted,so as to afford them proper length, andthey are so arranged that theouter end of the frame member 10 on each bar will form a corner with theouter end of a member 11 on the frame-bar to which it is at rightangles, and said ends are joined bythe introduction ofthe end of the barmember l1 between the sides a a of the bar member l0, so as to effect alapped engagement of these sides with the `part 1l.

Thereticulat'ed screen Wire-cloth l2 is cut of propersize and form topermit each edge thereof to be introduced between the clipflanges c on amember 10 of a corresponding 'frame-bar, this being obviously effectedbe fore the frame-bars are assembled to provide a border-frame for thescreen material. `f A triangular corner-piece 13 of plate metal isprovided to strengthen each corner of the screen-frame, and eachcorner-piece is slid` ably inserted between the screen material 12 and arespective corner of the border-frame. Perforations (l are formed in theframe members 10 11 at each corner, and the cornerpiece 13 is similarlyperforated in alinement therewith, so that small split keys CZ' or otheravailable securing devices may be passed through the perforations CZ andclenched or otherwise fastened therein, which will secure the frame-barstogether and upon the screen material 12. After the frame andcornerpieces have been secured upon the screencloth 12 the frame-barsmay be liattened thereon, so as to stitfen the screen-frame and assistin holding the screen-cloth by the use of a mallet or hammer in anobvious manner. Assuming that the screen iste be placed in awindow-frame provided with window-shutt ters or exterior slatted blindswhich must be opened and closed, a hand-hole is formed in the screencloth l2, near the lower edge thereof, and a small door is slidably heldthereat for the closure of the hand-hole when not in use as a means forreaching through the screen to manipulate the blinds. The hand-holeclosure may be a flat piece of screencloth 14, (shown in Fig. 1,) havinga rectangular frame 15 of sheet metal clipped upon the edge of thescreen-cloth, said borderframe being held to slide vertically in theguide-flan ges 16, formed or secured oppositely on the border-frame 17,secured on the screencloth 12, so as to surround the edge of therectangular opening cut therein. Preferably tongues e are formed on theborder-frame 17 by cutting the edges loose from the frame material, saidtongues 17.a passing through perforations in a mating border-frame 18,located oppositely on the screen-cloth at the opening therein, the endsof the tongues that project through the opening being bent so as toiiatten them against the frame-piece 18, which serves to bind theborder-frame firmly upon the screen-cloth.

It will be seen that by the described construction the closure or doorcomposed of the piece of screen wire-cloth 14 and borderframe 15 thereonand the loose engagement of said frame with the guide-flanges 16 willaord a convenient means for obtaining access to the blinds of a windowhaving the improvement for their manipulation, as before mentioned.

In Fig. 4 another construction of the handhole closure is shown,consisting in the provision of a box-like frame 19,having a sloped upperedge whereon a small screen-door 2O is imposed, said box-frame beingsecured over au opening in the screen-cloth material 12a, and the door20 is hinged thereon, so as to be adapted for easy elevation to permitthe protrusion 0f the hand through the opening in the screen material tomanipulate the window shutters or blinds, as occasion may require.

When the screen is positioned outside of the sash, it may with advantagebe removably held in place, as indicated-in Fig. l1, screw-studs g beinginserted into the windowcasement A at proper points, so that two of saidstuds may enter small perforations in the frame members of the screen atthe upper corners thereof and another pair of the studs enter likeperforations atl the lower corners of the screen-frame, the outer endsof these studs projecting from the Casement sufficiently to adapt themfor such an engagement. As the material .of the screenframe ismeasurably resilient, it may be bent laterally and then be sprung overthe projecting ends of the studs g, which upon engagement therewith willbear ou the adjacent edges of the ,'corner-pieces 13, that will havecontact with the studs when the screenframeassumes its normal condition.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A window-screen, comprising a rectangular piece ofscreen wire-cloth, and a sheetmetal border-frame therefor, each bar ofsaid frame comprising two telescoping sections, substantially U-shapedin cross-section, one section having return-bent flanges extended inwardand upward and embracing the edges of the other section that slidesbetween them,

said flanges also clamping upon an appropriate edge of the screenmaterial.

2. A window-screen comprising a rectangular piece of screen wire-cloth,a borderframe of sheet metal, each side bar of the frame comprising twosubstantially U -shaped sections that slide one upon the other, atriangular corner-plate for each corner of the frame, secured betweenthe screen-cloth and the lapped ends of the frame members, and means forsecuring said corner-plates to the frame members.

3. The combination with a window-screen, of a hand-hole closuretherefor, comprising a rectangular box-like frame open on top andprojected from the screen over a hand-hole, and a Hap-door hinged at oneedge on the frame so as to cover its opening when seated thereon.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CLAUDE B. WARNER.
